After Isaac came through Florida a lot of water was dumped.

I am at work now and my wife told me that the entrance to our community is flooded.

To what water depth have you guys steered the W126 through? Ankle, Knee?

Thanks,
Wolf

I've gone through water a foot deep ok but I had no choice as I was out in the boonies (bush). Drive very slowly. My advice is to wait.

I drove through at least knee deep water in mine accidentally once, but it died immediately after I got out of the water. It ended up drying out fine, but i'd consider myself very lucky I didn't get water in the intake or anything. I somehow didn't even get water in the interior surprisingly. If you absolutely have to drive through water go slow but keep your foot on the gas.

Don't do it unless you think you HAVE to. Yes, you can ease along very slowly in a foot of water, but why risk it. Just wait it out. Park car. Get a stick and wade home. Or stay in a motel.

Got out of the car, took shoes off and looked for the best route.

Had 14 inches at max on my route (had measurement tape with me). Then I measured alternator and intake on car. Removed intake hose just in case. (easy enough)

Went through it on my brakes - no issues. (1/4 mile)

Now we know :D (for 14 inches)

I saw one guy backing his Altima pretty fast through the water. He made it.

Thanks,
Wolf

I wouldn't attempt going through more than a couple of inches. We had some localized flooding up here a few weeks ago. Yesterday I completed an engine swap in a Lexus GS400 at work. It hydro-locked and broke a rod. Almost 6k to get him going again. Thankfully no water intrusion in pass compartment.

I saw people today getting stuck in less deep water. They seem to think the faster the better and create a huge bow wave. Water gushing all over the hood :crybaby2:

Wolf, That's why you need an suv as a daily driver. After my 4th MBZ, the wife thought I was nuts to add one. Stay safe! We dodged a bullet with the storm!

Check the differential, IIRC it is open at the top end due to the vent tube. If water gets in...

Best is to wait it out if unsure or if vehicle is lowered, etc. Or follow a larger vehicle wading through and creating a bow wave if really needed to cross.

For the engine the trick is to drive at walking pace (say 3-5 mph) so you create a bow wave. This will cause the water in front of the ar to 'dip'.

But the problem is anything that has breathers, like the trans and the diff. As these components heat up quite a bit under normal conditions, driving through cold water will cause them to cool really quickly, contracting the air inside and actually sucking in air. If the breather pipes or nozzles are submerged, it will suck in water turning the lubricant into goo.

Change the oil and the trans filter if you are unsure of how deep you went.

Good luck,

Peter (who drove Land Rovers in horrible conditions for many years).

I've gone through at least 40cms of water in both W126 and W124, W124 coughed a little (some water made it to the intake), but no other issues. I don't think it will be a problem on W126 as the intake is quite high and all the components are made to be highly water resistant...

Thanks for the word of wisdom! I will check the ATF.

Hey and Dobry Den to Prague! I visited your city three times between 2002 and 2005. Wonderful place to visit and party!
